I'm sure this is answered somewhere on here, but I don't have it in me to dig through pages right now. Can someone please tell me whether the knot is correct in this advice? It says to use this for a married couple on the outer envelope: Mr. John and Mrs. Samantha Holt. I know I could address as Mr. and Mrs. John Holt, but I prefer to keep the woman's first name. Is the knot right on this one?
